The joy and encouragement brought by the Texas victory to the entire Ming Empire is hard to describe in words. However, Zhu Cilang did not always immerse himself in it.

As a time traveler whose soul comes from later generations, he knew very well that the only one who sent the Qing Dynasty to recover Shandong this time was only a partial master.

If Dorgon was stimulated by this defeat in Dezhou, changed his overall strategy and tilted his troops to the eastern line, the Ming army would face tremendous pressure.

Of course, Zhu Cilang would not have any illusions about the Qing Dynasty. All he had to do was to prepare for the future and take all possible situations into account.

Since Nurhaci's rebellion, the Manchus have always lacked the ability to attack cities, so they mostly use the room to create chaos and open the city gates by relying on internal forces, and take down the city without bloodshed.

This tactic is naturally limited, and it was precisely because Huang Taiji saw this that he formed Wu Zhenchao - an army equipped with a large number of artillery.

Huang Taiji's strategic vision is still very vicious. He knew that the advantage of the Ming army lies in artillery. As long as the Eight Banners Army can catch up with the Ming army in this regard, they can have a full advantage in the duel with the Ming army.

Ning Jin's defense line created a huge shadow for Huang Taiji, so he naturally had an extremely urgent need to have a heavy artillery army to break open the solid city wall.

Unfortunately, only the Manchus in Liaodong lack artillery technology. Even Huang Taiji invested a lot of manpower and material resources, but Wu Zhenchaoha's artillery could not be comparable to the Ming army.

Until the Dengzhou Rebellion broke out, Kong Youde rebelled against the Ming Dynasty and surrendered to the Qing Dynasty, and brought a large number of Dengzhou artillery.

These artillery are all Flang machine cannons brought by Portuguese mercenaries from the Haowen Realm (Macao), and are the most advanced artillery of the same era.

With these cannons, Huang Taiji could order Liaodong craftsmen to imitate them. Although the imitation heavy cannons were not as good as the original shipment of Folang Jiren, they were still much better than the original rough cannons.

At this point, the Manchu artillery was no less than that of the Ming army.

In the original history, the three Shun kings including Kong Youde followed the Qing army into the pass in the 17th year of Chongzhen, and their main role was to attack Li Zicheng.

Together with Wu Sangui's troops, they charged for the Manchus as vanguards.

Among them, Wu Sangui, Shang Kexi and other troops followed Ajige from Datong to Yulin and went south to Xi'an from northern Shaanxi. Kong Youde, Geng Zhongming and other troops attacked Tongguan from Huaiqing, Henan under the leadership of Duoduo.

Li Zicheng responded by sending Li Guo to defend northern Shaanxi with Gao Yigong, and he personally led a large army to defend Tongguan.

In the end, Tongguan was lost. Li Zicheng knew that Xi'an could not be defended, so he made a decision to retreat again. After that, he was chased and beaten by the Qing army and eventually died in Jiugong Mountain.

If the Qing Dynasty used military forces against Shaanxi in late October of the 17th year of Chongzhen, before that, the Han army of Kong Youde and other troops would not have threatened Shandong.

But Zhu Cilang was worried that the butterfly effect brought about by the Dezhou victory would affect Dorgon's decision.

If Dorgon sent Kong Youde and other troops to Shandong, the situation would be completely different.

Although Dezhou is a strong city, it may be under great pressure to face the heavy artillery bombardment of the Han army from Kong Youde's troops. Perhaps these heavy artillery cannot directly collapse the city walls of Dezhou, but it can seriously damage battlements and defending the city equipment, causing the number of casualties of the Ming army to rise sharply.

Of course this is not what Zhu Cilang wants to see.

After thinking about it, Zhu Cilang decided to build a castle in the northeast of Shandong, namely Wucheng, Dezhou and Leling.

The so-called bastion is essentially turning the city block from a convex polygon into a concave polygon. This improvement allows the siege party to be exposed to several bastion surfaces no matter where the attack is made, and the defense party can use crossfire to multiple strikes on it.

The existing cities of the Ming Dynasty, including the fortress group built by Sun Chengzong in Liaodong, were all traditional four-sided cities.

If such a city is built strongly, it may not be a problem with ordinary artillery, but its biggest weakness is that it will require more soldiers to defend the city.

Just imagine, even if one thousand people are sent to guard each of the four walls, the entire city needs to be sent to garrison at least five thousand people. Five thousand people are 5,000 mouths. Even if there is no one in the city, all the food is supplied to soldiers, and the consumption is amazing.

When Huang Taiji's strategy of taking Daling River was to surround him without attacking him. Even if the Qing army could not directly attack the city, it could surround him and starve the Zu family army to death. The siege of the city was consumed. Although the Qing army consumed a lot, the Zu family army in Daling River City consumed even more, and it was a waste of money.

In the end, Zu Dashou ate all the people in the city and opened the city to surrender. Huang Taiji took down Daling River without any effort.

What if Daling River is replaced with a Western-style bastion group?

There is no doubt that the effect will be very good!

One of the major advantages of the bastion is that it requires very few defenders. A small bastion only requires a few hundred people, or even dozens of people, to withstand thousands of siege soldiers. Although these small bastions are not large in size, they are like a nail that is nailed there. Do you pull it or not?

If he doesn't pull it, he will disgust you there.

If it is pulled out, the battalion has a much higher ability to resist artillery strikes than that of ordinary cities, and it will eventually have to besiege the city.

But how can the bastion be surrounded by dozens of people and hundreds of people? How many people are sent to surround it?

If there are fewer people, it is impossible to surround them. If there are more people, food consumption is a big problem.

If the siege sends tens of thousands of people to surround a bastion with hundreds of people defending, how much food and grass will be consumed in the last six months?

The defenders in the bastion can completely reserve food for hundreds of people a year or even longer.

No matter how you look at it, the siege is suffering.

If it is a bastion group, it will be even more terrifying and can effectively prevent the cavalry from advancing. If you want to remove all these nails, you may have to do your best to the whole country.

Of course, the strength of the prismatic prismatic is based on specific historical conditions.

Only with sharp muskets can the bastion maximize its advantages.

This is also the reason why Zhu Cilang is so anxious to set up a firearms department and build high-quality muskets.

The brink can provide cross-fire power. If combined with a sharp musket, it can undoubtedly play the role of machine gun cross-fire.

Bastions and muskets are both indispensable. If the muskets are replaced with crossbows, the effect will be greatly reduced.

Of course, the stolen can't be absolutely invincible.

It was born because of the emergence of old-style artillery and its disappearance because of the widespread use of flowering bullets.

Zhu Cixuan can't even develop the flowering bullet himself now, so it is naturally impossible for the Qing Dynasty to produce it.

Therefore, the lever is invincible in this era.

The most important thing is that the cost of building a bastion is too low.

A bastion with dozens of people and hundreds of people stationed in the capital costs less than one tenth of a county town. With the current economic strength of the Ming Dynasty, a bastion group can be built in northeastern Shandong, completely blocking the Qing army.

The Qing Dynasty did not remove all these bastions, but it was impossible for the villages behind the bastion group to rob the towns!
